AM3352: AM335x U-boot时报错

Part Number: AM3352

专家好!

我目前使用ti-processor-sdk-linux-am335x-evm-09.03.05.02-Linux-x86-Install.bin

u-boot和kernel编译已经通过,但是放到板子上执行的时候报:不能初始化定时器,

具体错误如下:

U-Boot SPL 2023.04 (Jan 03 2025 - 14:14:26 +0800)
Trying to boot from MMC1


U-Boot 2023.04 (Jan 03 2025 - 14:14:26 +0800)

CPU : AM335X-GP rev 2.1
Model: TI AM335x EVM
DRAM: 512 MiB
Core: 161 devices, 18 uclasses, devicetree: separate
Could not initialize timer (err -19)

resetting ...

还请指导一下,非常感谢!
